What are the causes of Corrupt a file of AutoCAD / 3ds Max?

A number of factors can cause file corruption, including the following:

• Some component built in another program has been imported or referenced with an XRef.
• The scene failed to save properly due to a power failure or system crash.
• A poorly coded plug-in corrupted an object in the scene.

A Lot of Factors can be Reason of Corruption of File.

1.     Third-party applications running inside AutoCAD.

2.     DWG files created or saved by non-Autodesk or non-Real DWG products.

3.     AutoCAD terminated while saving the drawing.

4.     Old drawings used repeatedly over the course of years.

5.     Network anomalies (transmission errors, file locking, latent writing of data).

6.     Storage media degradation (bad sectors on a hard drive).

7.     Defective or failing RAM.

8.     Operating system issues.

9.     Power surges.

May be due to the AutoCAD file size is big or may be the system poor performance sudden existing of AutoCAD while editing the features or capturing the features or may be unspecified blocks inserted and so on...

RENDERING TIME .AND OPENING MORE THAN TWO WORKSHEET TIME 

Bad sectors/ bad clusters in hard drive causes difficulty to save/ retrieve files to/from hard disk.

autocad unexpectedly shutdown during saving

opening more than two worksheets at a time, Handling a huge project with more notations and structures.

i thinks its the electricity power off suddenly

or hang up of the program while saving

sometimes due to a number of unused layers and block defenation, files become heavy and starts corrupting s better purgeand audit the drawing

VERSION OF MAX TO AUTO CAD USUALLY I EXPERIENCE LIKE THAT BECAUSE OF LOW VERSION OF AUTOCAD AND YOU ARE USING LATEST VERSION OF MAX.

THE CAUSES OF CORRUPTION OF AUTOCAD FILES MAY BE FAILURE OF POWER OR VIRUS
